Azure VM windows 10 randomly go black

Today I was experiencing an unexpected issue with our Azure VMs running Windows 10. Earlier today, users across several VMs encountered a sudden problem: their screens went black, and the taskbar icons turned white. When they clicked on the icons, a message indicated that the program had moved. To restore normal functionality, we had to log off and back on for a large number of users.

This is the first time we’ve encountered such an issue, and we urgently need assistance in resolving it. Could you please guide us on where to look or provide any troubleshooting steps?
